Using afconvert to dowsample a wav (LEI16) file

I read that afconvert can take in a bitrate parameter, like so:

afconvert -d LEI16 -b 704000 old_file.wav new_file.wav

However, this bitrate parameter doesn't seem to do anything. I was expecting my file size to get smaller since I am switching from a 48kHz sample rate to a 22KHz sample rate.

What gives? Is the data parameter (LEI16) overriding the bitrate parameter?

Have you tried doing the command with the @?

for example,

afconvert --file caff --data LEI16@16000 --channels 1  fileOutputName.caf

or 

afconvert -f caff -d LEI16@16000 -c 1  fileOutputName.caf
